· JVASP-31153· NaAlB14

NaAlB14 is a sodium-aluminum boride ceramic compound belonging to the boron-rich intermetallic family. This material is primarily of research and industrial interest for its exceptional hardness and thermal stability, making it a candidate for abrasive and wear-resistant applications as an alternative to conventional cubic boron nitride or diamond in specialized machining and grinding contexts. Its development reflects ongoing efforts to create cost-effective superhard materials for cutting tool inserts, polishing compounds, and high-temperature structural applications where conventional abrasives prove insufficient.
